合成了带双羟基磷酸酯BBHP（butylbis（4-hydroxybutyl）phosphate），并研究了BBHP不同用量对合成的阻燃聚氨酯弹性体的阻燃和力学性能的影响。随着BBHP用量的增加，聚氨酯弹性体的阻燃性能提高，100％引张应力、拉伸强度、伸长率均不断下降，撕裂强度在BBHP添加量为12％时达到最大值。当BBHP用量在10％～12％，聚氨酯弹性体的氧指数达到27以上，力学性能和颜色均满足聚氨酯弹性体的要求．
A dihydroxyl phosphate called butyl bis（4-hydroxybutyl） phosphate was synthesized. The mechanical and flame retardant properties of TPU were investigated by different additive amount of BBHP. It was found that with the increasing of BBHP, the mechanical strength performance of TPU decreased, but the flame retardant of TPU improved. When the additive amount of BBHP came up to 12%, the tear strength of TPU was up to maximum. The oxygen index of TPU reached more than 27 with the adding quantity of BBHP from 10% to 12%. At the same time, the mechanical properties and color can satisfy the requirement of TPU.
